for Very High Speed Digital Subscriber Lines (VDSL) Using
Multiple Carrier Modulation (MCM) Line Coding
Status of This Memo
This document specifies an Internet standards track protocol for the
Internet community, and requests discussion and suggestions for
improvements. Please refer to the current edition of the "Internet
Official Protocol Standards" (STD 1) for the standardization state
and status of this protocol. Distribution of this memo is unlimited.

Abstract
This document defines a portion of the Management Information Base
(MIB) module for use with network management protocols in the
Internet community. In particular, it describes objects used for
managing the Line Code Specific parameters of Very High Speed Digital
Subscriber Line (VDSL) interfaces using Multiple Carrier Modulation
(MCM) Line Coding. It is an optional extension to the VDSL-LINE-MIB,
RFC 3728, which handles line code independent objects.

1. The Internet-Standard Management Framework
For a detailed overview of the documents that describe the current
Internet-Standard Management Framework, please refer to section 7 of
RFC 3410 [RFC3410].
Managed objects are accessed via a virtual information store, termed
the Management Information Base or MIB. MIB objects are generally
accessed through the Simple Network Management Protocol (SNMP).
Objects in the MIB are defined using the mechanisms defined in the
Structure of Management Information (SMI). This memo specifies a MIB
module that is compliant to the SMIv2, which is described in STD 58,
RFC 2578 [RFC2578], STD 58, RFC 2579 [RFC2579] and STD 58, RFC 2580
[RFC2580].
2. Overview
This document describes an SNMP MIB module for managing the Line Code
Dependent, Physical Medium Dependent (PMD), Layer of MCM VDSL Lines.
These definitions are based upon the specifications for VDSL as
defined in T1E1, European Telecommunications Standards Institute
(ETSI), and International Telecommunication Union (ITU) documentation
[T1E1311, T1E1011, T1E1013, ETSI2701, ETSI2702, ITU9931, ITU9971].
Additionally the protocol-dependent (and line-code dependent)
management framework for VDSL lines specified by the Digital
Subscriber Line Forum (DSLF) has been taken into consideration
[DSLFTR57].

The MIB module is located in the MIB tree under MIB-2 transmission.
The key words "MUST", "MUST NOT", "RECOMMENDED", and "SHOULD" in this
document are to be interpreted as described in [RFC2119].
2.1. Relationship of this MIB Module to other MIB Modules
The relationship of the VDSL Line MIB module to other MIB modules and
in particular to the IF-MIB, as presented in RFC 2863 [RFC2863], is
discussed in the VDSL-LINE-MIB, RFC 3728 [RFC3728]. This section
